Abstract
The reversal of voltage polarity is essential in HVDC cable systems with Current Source Converters (CSC), since it enables to revert the direction of the power flow. In a previous paper by the authors a life model for HVDC cables subjected to voltage polarity reversal was developed and applied for predicting the life of HVDC cables subjected to a voltage polarity reversal test. In that model, a heuristic procedure was developed for determining the relaxation time constant for the redistribution of space charges within the insulation after voltage polarity reversal. In this paper the model is refined according to a novel approach based on manufacturers’ experience with MIND HVDC cables.
